The senior partner of our Litigation Group, Irving is recognized and respected by clients, colleagues and judges as a highly skilled, forceful and effective advocate.

Irving has extensive experience in all aspects of business litigation. He has successfully represented his clients in disputes involving a wide range of issues including, banking, real estate, commercial transactions, corporate law, taxation, and estates and trusts. Other law firms and accounting firms regularly refer clients to Irving as counsel. His clients include large corporations and businesses (public and private), banks, financial institutions and other lenders, entrepreneurs and individuals. 

Irving's strategic approach and understanding of his clients' objectives enables him to quickly assess the strength of their case and give sound and trusted advice on the best strategy to effectively advance their interests.
